What is OpenAI

The AI lab behind ChatGPT and the GPT models — a major new surface where people discover brands and answers.

Official site

Overview

OpenAI is the AI research company that built the GPT family of models and ChatGPT, the assistant that pushed conversational AI into mainstream use. Its models are available directly through ChatGPT and via an API that powers a large share of the AI features in other products.

For marketers, ChatGPT has become a genuine discovery channel. Its web-browsing and search features cite sources, so the way your content and entity presence are structured now affects whether an AI recommends you — a discipline usually called GEO or AI search visibility.

What they do

OpenAI develops large language and multimodal models, ships them through ChatGPT and its API, and provides the crawlers that gather and reference web content. Its models also underpin many third-party assistants and agents through the API.

  • ChatGPT: consumer and business AI assistant with web search
  • GPT models via API: the engine behind countless AI features
  • GPTBot and OAI-SearchBot: crawlers that index and cite the web
  • A commercial partnership with Microsoft on models and compute

Why they matter for your site

When ChatGPT answers a question, it may cite or paraphrase specific pages. Whether yours is chosen depends on clear, well-structured, trustworthy content and whether you allow OpenAI's crawlers to access it. Blocking those crawlers in robots.txt keeps you out of that answer set entirely.

How REO Rank works with their platform

We audit robots.txt and crawler access for GPTBot and OAI-SearchBot, structure content into clearly answerable passages, and strengthen entity signals so ChatGPT is more likely to surface and cite you. We also build products on OpenAI's API where an AI agent or assistant is the right tool for a client.

Why it matters

OpenAI is the AI research and deployment company behind ChatGPT and the GPT family of models, and it is the organisation most responsible for bringing large language models into mainstream use. It matters because ChatGPT's launch in late 2022 triggered the current wave of generative AI, reshaping how people search, create and work — and because ChatGPT is now itself a major search-and-answer surface that businesses want to be cited by. For anyone in search and marketing, OpenAI's products are both a tool they use and a discovery channel they need to be visible in.

Its significance to search and marketing

OpenAI matters to marketers on two fronts. As tools, its models power a huge range of AI features and workflows — content assistance, support agents, coding, analysis — that teams build on via its API. As a discovery channel, ChatGPT (especially with web browsing and its growing search capabilities) answers questions for millions of users by synthesising and citing sources, making it a place brands increasingly want to be surfaced and cited — the core concern of GEO (generative engine optimization). OpenAI's deep partnership with Microsoft also connects it to Bing and Copilot. Its trajectory and product decisions materially affect how AI-mediated discovery evolves.

  • As tools: its models (via API) power content, support, coding and analysis
  • As a channel: ChatGPT answers and cites sources for millions — a GEO target
  • Deeply partnered with Microsoft, connecting to Bing and Copilot
  • Its decisions shape how AI-mediated discovery evolves

In practice

For marketing and search teams, OpenAI shows up in two practical ways. First, its models are a building block — used directly or via its API to power content tools, assistants and automation — where the usual cautions apply (grounding to reduce hallucination, guardrails, evaluation). Second, being visible in ChatGPT's answers is a growing goal: as more users ask ChatGPT questions instead of searching, being a source it draws on and cites is part of staying discoverable, which is what generative engine optimization addresses. Watching OpenAI's product moves — search features, browsing, the assistant ecosystem — is part of tracking where discovery is heading.

  • Use its models (directly or via API) with grounding, guardrails and evaluation
  • Aim to be a source ChatGPT surfaces and cites (GEO)
  • As users ask ChatGPT instead of searching, its answers become a discovery channel
  • Track OpenAI's product moves as part of the AI-search shift

Common questions

OpenAI — questions

Straight answers on how this fits your marketing and build.

How do I get my brand mentioned in ChatGPT answers?
There is no ad slot to buy. You earn mentions by publishing clear, accurate, well-structured content, building a strong entity presence across the web, and allowing OpenAI's crawlers to access your site. This is the core of GEO or AI search visibility work.
Should I block OpenAI's crawlers in robots.txt?
Only if you have a specific reason to. Blocking GPTBot or OAI-SearchBot removes your pages from the pool ChatGPT can cite, which usually costs you visibility. Most brands should allow access unless there is a clear content-licensing or privacy concern.
Why should marketers care about OpenAI?
On two fronts: its models are tools teams build on (content, support agents, automation via its API), and ChatGPT is a fast-growing discovery channel that answers and cites sources for millions of users. As people increasingly ask ChatGPT instead of searching, being a source it surfaces and cites — the goal of generative engine optimization — matters for staying discoverable.
What is OpenAI's relationship with Microsoft?
A deep partnership — Microsoft is a major investor and partner, integrating OpenAI's models across its products (Copilot) and infrastructure. This connects OpenAI's technology to Bing and Microsoft's ecosystem, which is part of why Bing visibility has grown more relevant in the AI-search era, since these AI answer surfaces draw on connected indexes and models.
